Listen to your racquet and perfect your game!
RacquetTune ensures that your racquet is ideally suited to your style of play. Simple and straightforward to use, the app uses the sound generated by tapping the strings to calculate the tension with high accuracy. In addition, the interactive swingweight calculator aids in customizing your racquet to fit your own stroke pattern, while the stiffness calculator allows you to simulate different racquet configurations.
RacquetTune not only makes it easier to decide when it is time to restring, it is also an invaluable tool when testing different racquets and strings and in identifying which of your racquets is best suited for different types of games. RacquetTune also allows you to check whether your stringer is consistent in his work.
RacquetTune includes the following user-friendly tools:
Tension measurement
- Quickly determines the tension and stringbed stiffness.
- Able to detect changes in tension as small as 0.1 kg/0.2 lb.
- An accuracy indicator ensures results are consistent.
- Graphical presentation of sound waves helps you find the ideal way of tapping the strings.
- Settings can be customized to serve tennis, squash, racquetball and badminton racquets, respectively.
- View the tension history for each racquet as a list or a graph.
- Email a spreadsheet with test data.
Swingweight calculator
- Add as many weights as you wish to the frame.
- Move and change weights to visualize how swingweight, balance and sweet spot location are affected.
- Enter target values for the racquet and let RacquetTune distribute the weights automatically.
Stiffness calculator
- Simulate various racquet and string configurations
- Vary tension, string type and racquet head size.
- Shows load-displacement curves, stiffness and elastic energies
- Handles the large deformations encountered in actual play

RacquetTune has been featured in tennis magazines in USA, Italy, France, Germany, Sweden and Norway.
"The app is very, very impressive. I get more tension diagnostic questions than just about anybody in the universe, so this is a very good thing to be able to recommend."
Jonathan Wolfe
US Racquet Stringers Association
Note, that the actual string tension in the racquet and the setting seen on a stringing machine are two different things and therefore incomparable - more information can be found at racquettune.com.

A phenomenal tool for maintaining consistency and dialing in your racket
Racket tune is a fantastic tool for checking racket tension and dialing in your swing weight, the added twist weight calculation tool provides invaluable insight into weight placement locations and how they effect your overall swing weight as well as twist weight simultaneously ! This is one tool that no serious tennis player, coach or pro should be without, even if all you use it for is to check the tension of a racket after a few hours of playing or possibly right after it has been strung this app will allow you to be consistent,
to get real information and it is the only truly accurate way in the world to check actual racket tension after it has been strung. I cannot more highly recommend this app !!
It works for me
To get it right, get a new string on your racquet and play with the value of the string factor until match the value tension of you new strings.. it works for me 👍
I must be doing it wrong
I restrung my racquet at 55#. This app said the tension was 40.2# right after I finished. I checked the string factor and ensured that I’d entered the correct values all the parameters (e.g. string pattern, racquet face size). I followed the measurement procedure to the letter.
I could believe a couple lb. change but 15? Nyet. The racquet plays like 50-55.
A Gamma String Tension Tester said the two center main strings were at 55# and the two center cross strings were at 39 and 40#.
Why are other users getting numbers close to the tension at which they strung?
Not even close for this app. Sorry
Not accurate
Don’t waste your money
Amazingly Accurate
It’s almost too good to be true. I get readings and I think, no, it must be wrong. It can’t be a mistake a made. Sure enough, I did something wrong.
When I string exactly the same, I get the exact same output. This is an amazing app.
It has helped me string better and learn more about how my string tension changes over time.
Well done!!
Pretty inconsistent
I place the phone on a table, lay the racquet about an inch above it and use a wooden spatula to hit the strings. It has a delta of +/- 4-5 lbs and is hard for me to trust.
Better than I expected
I have had this App for a week now and the results have been much better than expected! I use it to find out how much tension drops after each playing session.
String factor accuracy is crucial
Fantastic app. Incredibly useful to graph how the racket loses tension over time. Readings are very accurate. (note, if I’m stringing a poly, I can sometimes lose up to 10% by the time it’s off the stringer, then maybe another 10% over the next 48 hours) String factor accuracy is crucial, and the online database can be hit or miss, you’ll see lots of variation in there. You should measure this yourself to make sure it’s accurate, because it will greatly affect the reading. I use the weight method, and that’s worked out well for me so far.
Not reliable
It doesn’t give you consistent tension. It gives me different tension every time. Total garbage.
Not consistent or accurate
90% of the time I could no get the app to pick up a tension despite following the guides
Racket strung at 47lbs confirmed on ERT tension tester machine. When I got racket tunes to pick up, it showed 58lbs. Used the correct string set up.
At best this app might be able to tell you which of your rackets is strung a bit tighter. But that’s all. Just a gimmick.
Wouldn’t waste your money
